Interesting. I feel similarly, but I would place my joy in exploration rather than discovery. I'm not interested in discovery, where I take only the rules/components and try to discover the best plays and strategies. I don't have the time or the inclination to endure the dead ends and plays of failed strategies. (Some people love that, they want to find the best plays themselves; not me.) I want a map, a guide, then my joy is in taking that map, and applying it to the game state I'm in.
Thus, I love reading strategy guides, and following instructions. I build Lego sets frequently, but I never build My Own Creations. For me, the fun is in execution. Thus, complex games give me more paths to walk, more levers to pull. Simple games get boring, and often end up in the deeply iterative analysis that you see in Chess/Go: if I do this, then they'll do that, so then I need to do this, etc. etc. etc. Not fun at all for me, and why I largely avoid most abstracts too.
In a related note, this is also why I ended up in SysAdmin, not Dev; I want to implement the awesome programs that other people make; I have little interest in creating something new myself.
